SUCTION-NOZZLE FOR DUST AND ASK REMOVING DEVICES.

Application filed March 17, 1909.

' 0 all whom it may concern:

Be it known that I, Enron Pansnxnono, a subject of the German Emperor, and a resident of Syracuse, in the county 0 nondaga and. State of New York. have invented a new and Improved Suction-Nozzle for Dust and Ashes Removing Devices, of which the following is a full, clear, ant exact description.

This invention relates to means'for separating and removing fine ashes from such waste products of fuel combustion as accumulate in the ash pits of steam generators or below the fire chambers in hot air furnaces. The purpose of the invention is to provide novel, simple and practical details of construction for a dust and ashes suction nozzle and its combination with air exhausting means, which enable the speedy and thorough removal of fine ashes from the ash pit of a furnace or the: like, and the transfer of such material to a point of discharge.

The invent-ion consists in the novel construction and combination of parts, as is hereinafter described and )ended claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side view of the improve' ment applied for the removal of fine ashes from the ash pitof a combustion chamber 0 a steam generator; Fig. 2 is an enlarged side view of the improved suction nozzle, and a pipe extended therefrom; Fig. 3 is a reseen in the direction of the arrow 0; in Fig. 2; Fig. 4 is a sectional side view on the line 4 4 in Fig. 3; Fig. 5 is a transverse sectional view on the line 5-5 in Fig. 4; Fig. 6 is a trans verse sectional view on the line 6-43 in Fig. at; Fig. 7 isa transverse sectional, view, on the line 7-7 in. Fig. l; and Fig. 8 is a reversed plan view of a slightly modified form of the improvement.

The body of the improved nozzle is cast or otherwise formed into shape from a suitable metal, and essentially comprises an arched top wall 10, the form of which is clearly shown in Figs. i, 5 and 6, having a curved apex a, and similarly inclined sides I), that merge at their lower ends in the up Specification of Letters Patent.

right side walls 0. The forward end 7) of the body 10 is shown solid but may be recessed and slopes downward, this inclined wall joining a flat bottom, the sides thereof and said bottom being flattened, appears at b in Fig. 3, and the latter terminates at c in an upward and rearwardly inclined wall. The rear end of the body 10 is formed integral with a tubular extension ll, and as appears in Fig. 4, a transverse partition (1 extends forward from the bottom of said conduit or tubular extension, the latter preferably having an offset bend c at its junction with the body 10. The partition cl engages the inner surfaces of the side walls (1-, near their points of connection with the inclined sides 7), as is clearly shown in Fig. 6, and as appears'in said view, a plurality of spaced ribs-g project downward from the partition (l, their free lower edges 51 being level with the corresponding edges on t side walls 0. The partition d ternii ates at al thus permitting an opening h to be formed between the transverse wall 0' and the forward edge d of the partition, said opening being partially covered by the thin ribs g that extend forwardly, and at their forward ends are'-j )ined to the transverse wall a. A suitable number of the spaced ribs g are einployed,'and each rib on its lower edge is formed with a series of teeth 2', said edges occupying the same horizontal plane with the lower edges of the side walls 0, that are also serrated on their edges.

To adapt the improvement for effective service, the tubular portion 11 is given sutiicient length to adapt it to serve as a conduit for fine ashes, through the same to a selected point of discharge, which may be into a receptacle such as an ash canor the like, an exhaust fan blower or the like (not shown) being introduced in the conduit.

In use, the pipe 11 is taken hold of as a handle,

and the nozzle 10 is inserted into the ashes that may a fire chamber of a steam boiler or hot air furnace. The operator thoroughly stirs the pile of ashes, that may be fine dust mingled with coarser particles, by dle down and then raising it, thus correspondingly moving the front end of the nozzle so as to agitate the mass of material; therefore as a current ofair in the direction of the arrow 1n Fig. l is produced by the exhaust fan or other means, the fine ashes have accumulated below 1 pressing the handischarge therefor.

1. A suction nozzle, comprising an elongated body having a horizontal partition extending" between the sides of the bed and terminating short of the front end thereof, whereby an opening is formed, and spaced ribs projecting from. the partition flush with the sides of the body, said ribs extending across said opening and secured to the forward end of the nozzle.

2. A suction nozzle, comprising an elongated body having a tubular extension at its rear end, a horizontal partition extending from the bottom of the extension between the sides of the body above the lower edges of the same, said partition terminating short of the front end of the body, and spaced ribs depending from the partition flush with the sides of the body, said ribs extending to the front of the body and secured thereto.

In a device of the character described, the nozzle, embodying an elongated hollow body, an arched to wall thereon, a tapered front end, depending side walls, a tubular extension on the rear end of the bod a will be drawn into the opening it, and thence conveyed through the conduit to a point of It will be seen that the ribs 9 prevent the entrance of lumps of refuse that would obstruct the passage of the fine ashes through the conduit 11, and they also facilitate the I crushing of caked ashes by their impact thereon produced by proper manipulation of the nozzle, the teeth 2' serving to disintegrate the lumps or cinders i engaged by the ribs 9. 1

It will be noted thatthe sloped sides 6 of J the arched top of the nozzle 10 permit the ashes to drop therefrom when the implement is in use.

In Fig. 8 a modified form of the device is shown, In this construction the nozzle is bifurcated, providing two similar nozzles 10",that are joir. together at their rear ends, that merge 12 into a tubular conduit 12, each of said twin nozzles being formed similarly to the nozzle 10, hereinbefore described. The device as constructed in Fig. 8, provides a larger surface for engagement with a pile of ashes, and be transverse partition extended forward one advantageously used where there is a body the lower side of the partition, the body of ashes'of considerable size to be removed from an ash pit.

It will be seen that the described nozzle can be used as a screenin 'device for coal mixed with fine ashes, especially when anthracite coal is burned in a furnace, as by the insertion and free manipulation of the nozzle on a quantity of mingled coal and ashes, ,the material will be practically screened and the coal thus separated may be burned in the furnace.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

that are forcibly tition at its forward end and the rear wall of spaced ribs having serrations in their lower edges and extended from the tubular extension to the tapered front end and crossing the opening thereat.

In testimony whereof I have signed my name to this specification in the presence of two subscribin witnesses.
